As Martina walked into her bathroom, she couldn't help but feel a sense of anticipation building within her. She'd been experiencing some unusual bowel movements lately, and today was the day she was finally going to do something about it. She closed the door behind her, leaning against it quietly, before reaching into her underwear and removing the thick, smooth dildo she'd bought just for this occasion.
She tossed her underwear aside, revealing her shapely ass, and slicked the dildo with a generous amount of lube she kept next to the toilet. Gripping it tightly, she knelt down in front of the toilet bowl, her heart thumping in her chest as she positioned the dildo at her rear entrance.
Martina groaned as the cold, hard dildo pressed against her warm, soft skin, sending shivers down her spine. She moaned louder, pushing back against the dildo, feeling it slowly slide inside her asshole. It was a sensation she'd only fantasized about, and now that it was happening, she couldn't believe how good it felt.
Once the entire dildo was buried inside her, Martina leaned forward with her elbows on her knees, taking deep breaths as she tried to calm herself down. She knew she needed to relax or else she wouldn't be able to take the thick thermometer she'd bought.
Suddenly, Martina felt a new sensation as the thermometer slipped into her soaking wet pussy. She moaned again, imagining how it would feel once it was buried deep inside her tight ass. She closed her eyes, trying to focus on the feeling, lubing up the thermometer with saliva before positioning it at her deflowered entrance.
With a deep breath, Martina pushed the thermometer into her ass, gasping as it slipped past her resistance. She gripped the dildo tightly, riding the wave of pleasure that washed over her. She could feel the thermometer's full length buried inside her now, and all she could do was moan in ecstasy.
As Martina began to move back and forth on the dildo, grinding against the thermometer buried inside her ass, steam began to rise from the shiny porcelain toilet bowl. She panted, her breath coming in short bursts, her body shaking with release. It was an experience unlike any other, and Martina knew she would never forget it.
After what felt like an eternity of pure bliss, Martina finally collapsed onto the floor, panting heavily. She slowly pulled the dildo and the thermometer from her tired, sore, but incredibly satisfied body. As she sat there, basking in the afterglow of her self-induced orgasm, Martina couldn't help but wonder where this newfound love for ass play would take her next.
